Title: Oscillating circuit for high frequency
Inventor: NEZU TAKASHI
IPC: H03B5/00
Filed: 1981-04-30
Abstract: PURPOSE:To achieve stable oscillating operation by eliminating a phase shift due to a feedback loop by composing the feedback path of only a resistance equivalently. CONSTITUTION:A feedback loop is an inphase feedback path of a transistor TRQ2, a TRQ5, a diode D2, a diode D3, a TRQ4, a resistance R3, and a TRQ1, and signal transfer from each element to the next trailing element is performed with low impedance. Further, the emitters of the TRs Q1 and Q4 are grounded through not a resistance, but a current source, so impedance between the emitters of the TRs Q1 and Q4 and the earth point is infinite, allowing the emitter sides to have no relation with feedback signal conditions. Therefore, an output signal is equivalently fed back to the TRQ1 by the resistance R3 as it is.

Title: Memory protecting circuit
Inventor: KUWAKI KATSUHIKO
IPC: G06F12/16
Filed: 1988-03-17
Abstract: PURPOSE:To prevent memory data from being destroyed by stopping the operation of a CPU at first when a main power source is interrupted, obtaining a hold condition, after that, causing a memory to be in an access prohibiting condition and lowering the voltage of the main power source. CONSTITUTION:Together with the interruption of the main power source, a main power source supplying circuit 11 sends a power source interruption detecting signal 110 to a CPU19. Based on this signal, the CPU19 executes a prescribed processing and after that, goes to the hold condition and the access to a memory 8 is stopped. Next, the main power source supplying circuit 11 sends a memory access prohibiting signal 120 to a memory access prohibiting circuit 7. Based on this signal, the memory 8 is caused to be in an unoperatable condition and the data contents of the memory 8 are held. When a constant time passes after the sending of a prohibiting signal 20, the voltage of the main power source is started to be lowered. Then, when the voltage is lower than the voltage of an auxiliary power source 2, a power source switching circuit 13 switches a power source from the main power source to the auxiliary power source 2 and the data contents of the memory 8 are held. Thus, the memory data can be protected.

Title: Trigger circuit of electric shutter circuit for camera
Inventor: KUMETA TAKUMA
IPC: G03B7/083
Filed: 1981-04-30
Abstract: PURPOSE:To attain accurate control of exposure by means of a capacitor which is also used as an alarm, by delaying the trigger of a control capacitor when an exposure alarming state is shifted to an exppsure value controlling state and then biasing the both-terminals potential of the capacitor to a constant state. CONSTITUTION:A switch S2 is closed at the 2nd stage of a shutter release to shift an exposure alarming state to an exposure value controlling state. Thus the output of the 5th stage F5 of flip-flops F1- that forms a delaying counter is inverted to a high level after the counter is set and in the lapse of time 4ms, etc. As a result, an RS type FF formed with NAND gates NAG11 and NAG12 is set via NAND gates NAG4 and NAG3, and transistor T2 is turned off via an NOR gate NOG1, etc. Thus a capacitor C1 that is also used as the function to give the alarm for the insufficient luminance, the camera shake or the defective exposure is sufficiently discharged in the delay time to be triggered to perform an integration of light volume for the control of exposure in the state under which the both-terminal voltages are biased to a certain level. In such a way, accurate control of exposure is possible with a capacitor that serves also as the function  to give alarms.

Title: Voice information transmission system
Inventor: USU KATSUNORI
IPC: H04J3/00
Filed: 1989-03-20
Abstract: PURPOSE:To stably offer PB service which utilizes a high-efficiency circuit by passing a non-voice signal through a digital circuit which uses a high- efficiency voice encoding and decoding device (high-efficiency CODEC) with processing delay in addition to a voice signal. CONSTITUTION:Push-button(PB) character data when received from a digital line 9 is decoded by a PB generator 6 into a PB signal, which is outputted to an output line 13 without any delay, and when the PB character data as received data is converted into voice encoded data, the data is decoded by a voice decoder 5 into a voice signal, which is outputted to an output line 13 a specific time later; and the PG generator 6 outputs a no-voice signal. Thus, when the output signal of a multiplexer 3 is switched from the PB signal to the voice signal, the switching of a switch circuit 71 is delayed by longer than a specific time, so a PB signal of bad quality passed through the high-efficiency CODEC is not outputted to the output line 13.

Title: Plasma x-ray generating device
Inventor: KATO YASUO
IPC: H01J35/22
Filed: 1985-04-01
Abstract: PURPOSE:To reduce variation of the position of the hot spot radiating X-ray formed from a high temperature and a high density plasma from the axis, by making the outside electrode longer than the inside electrode, and arranging the outside electrode to surround the space at the end of the inside electrode. CONSTITUTION:The length of a cathode 2 is longer than that of a cathode 1 and the cathode 2 is arranged to surround the space at the end of the cathode 1. Since the hot spot of plasma is formed in a range 0-20mm from the tip of the cathode 1 along the axis, the space where the hot spot is formed is surrounded by the cathode 2, and a strong stability toward the axis acts proportionally to the distance the hot spot is apart from the axis. Because the amount of the stability when the hot spot is apart from the axis is reversely proportional to the square of the inner diameter, the amount of the stability acting to the plasma is about 2.5 times. Therefore, the variation of the hot spot position from the axis is reduced to 1:2.5.

Title: Grain particle detector for grain particle moisture measuring apparatus or the like
Inventor: MORI TAIICHI
IPC: G01N27/04
Filed: 1989-03-17
Abstract: PURPOSE:To achieve higher dry control and moisture stop control accuracy by detecting whether grain particles are refined or unrefined depending on light from a projector for irradiating the grain particles in transit to detect a correct grain particle moisture. CONSTITUTION:A part of grain particles being dried by the repeated circulation with a drying machine are supplied to transfer rolls 1 of a grain particle moisture measuring device. The grain particles are delivered to a spiral groove 2 one at a time and driven out to be supplied between detection rolls 29. The grain particles are delivered to a circumferential part of the detection rolls 29 to be crushed being grasped therebetween while a moisture is detected. A grain particle moisture of 32 particles is detected one at a time and a mean of the moisture detected is computed. An average moisture value is equivalent to one batch of grain particle moisture. The grain particles in transit with the transfer rolls 1 are checked whether to be refined or unrefined by light irradiated from a projector. For example, when the grain particles detected are unrefined, the unrefined particles undergoes a treatment to remove the moisture detected and thus, the grain particle moisture of the refined particles alone is detected.
